Unauthenticated remote read of stored form data with no interaction gives AV:N/PR:N/UI:N; missing access check makes it low-complexity; only confidentiality is affected (C:H, I/A:N).

Lifecycle Timeline
4DescriptionCVE.org
The front-end Submissions view did not enforce access control. An unauthenticated visitor could therefore list a form's submissions.
AnalysisAI
Unauthenticated information disclosure in the Convert Forms extension for Joomla (versions 2.5.0 through 5.2.2) lets any anonymous visitor enumerate and read a form's stored submissions because the front-end Submissions view fails to enforce access control. Submitted data frequently contains PII such as names, email addresses, phone numbers, and free-text messages, so exposure can be significant. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Technical ContextAI
Convert Forms is a commercial drag-and-drop form-builder extension by Tassos Marinos (tassos.gr) for the Joomla CMS, used to create contact, subscription, and lead-generation forms whose responses are stored server-side and normally reviewed through an authenticated back-end. The vulnerability is a CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) missing-authorization flaw in the component's front-end Submissions view: the view renders stored submission records without checking whether the requesting session is authenticated or authorized, so the access-control gate that should restrict this data to administrators is simply absent from that code path.
RemediationAI
No vendor-released fixed version was identified in the provided data; the last affected version is 5.2.2, so a patched release above 5.2.2 is the expected fix but is not independently confirmed here - check the vendor advisory and update to the current release at https://www.tassos.gr/joomla-extensions/convert-forms and the NVD entry at https://nvd.nist.gov/vuln/detail/CVE-2026-65758 before upgrading. As an interim compensating control until a confirmed patched version is applied, restrict or block front-end access to the Convert Forms Submissions view (for example, deny the submissions view route/task at the web server or WAF layer, or via a Joomla access-level restriction), accepting the trade-off that any legitimate front-end submission-review workflow will break. Where feasible, purge or minimize sensitive data retained in stored submissions to reduce exposure if the endpoint is reached.
